Nowadays i am experimenting with XBee® ZB SMT modules. I have communicated with XB24CZ7PIS-004 over UART with no problem. I send data to the module and received it from an zigbee to ethernet router. But when i try to communicate over SPI, i couldn’t.
I am sending a 0x55 byte over SPI to the Xbee module once in every second. In this figure, you can see the preferred SPI clocking at the upper image and you can see the my SPI clocking in the lower image.
In the figure:
• 2nd channel is Chip Select
• 1st channel is MOSI
• 4th channel is clock
Communication is one way so i did not included MISO signal. I think i implemented SPI communication in correct way but as i said, i cannot get any data from the router.
Can you help me on this issue?
